I run Khumos in that size, generally 28-32 on front and 32-34 on the back.

thankyou , i'll try that out
Have you tried the chalk test?
Draw a (fairly thick) line across the tyre in chalk and then go for a drive.
If the chalk wears out more in the middle than the sides = tyre is overinflated
If the chalk wears out more on the sides than the middle = tyre is underinflated
Even wearing down of the chalk = correct pressure.
